Title: Tenter clip and method of manufacture
Inventor: MITCHELL DEREK
IPC: D06C3/04
Filed: 1970-09-09
Abstract: 1277835 Tentering fabrics PROCTOR & SCHWARTZ Inc 9 Sept 1970 43166/70 Heading D1S A tenter clip comprises a first portion 17, Figs. 2 and 3, having a base 21 providing means 13, 14 for securing the first portion to tentering apparatus and having a pair of flange parts 22, 23 extending from the base 21 integral therewith, a second portion 18 secured to the portion 17 at the parts 22, 23 and gripper means 6, each of the parts 22, 23 having an opening 24, 25 therethrough aligned with that in the other part, the means 6 having at least one opening therethrough, and a pivot pin 7 extending through the openings 24, 25 and the opening(s) in the means 6 to pivotally connect the means 6 to the portion 17. The clip comprises a body 2, Fig. 1, having a pinplate support 3 mounted thereon by a pivot pin 4 and biased to an inoperative position by a spring 5. A gripper 6 having a clamping jaw 16 is mounted on the body 2 by a pivot pin 7. The support 3 carries a pinplate 11 of elastomeric material and having pins 12 and is lockable in the horizontal position of Fig. 1 by the location of a pin 8 behind a shoulder 9. The portions 17, 18 and the support 3 are stamped from stainless steel sheet metal. The portion 17, Fig. 3, comprises a base 21 having slots 13 and an aperture 14 to secure to clip to a roller or slide construction 15, Fig. 1, to slide along a rail. The flanges 22, 23 are bent about lines 19, 20 and the pin 7, Fig. 1, is received by aligned openings 24, 25, Fig 3, and the pin 4 by aligned openings 26, 27. The portion 18, Fig. 4, comprises parts 33, .. 38 which are bent to interfit with the portion 17, see Fig. 2, and are flash or spot welded thereto. Slots 39 in the part 36 receive flanges 43, 44, Fig. 8, of the support 3 and slots 41, Fig. 4, receive rollers 42, Fig. 1, mounted on the gripper 6 by pivot pins 8. When the support 3 is bent about lines 49, 50, 61, 62, openings 45 are aligned and receive the pin 4. Three slots 40, Fig. 8, receive keys (54), Fig. 10 (not shown), of the pin plate 11. When it is desired to use the pin plate 11, the support 3 is rotated by rollers, for example, at the entrance of the tenter run. As the support 3 rotates to horizontal position, the projections of the pin 8 beyond the rollers 42 are contacted by cam surfaces 10 and rotated slightly about the pin 7 to fall behind the shoulders 9 to lock the support 3 in opeartive position. When the end of the run is reached, the support 3 is released and causes clockwise rotation of the gripper 6 about the pin 7. Upon initial clockwise rotation of the gripper 6, the spring 5 permits a slight counterclockwise rotation of the support 3 about the pin 4 until the pin 8 is moved from its position behind the shoulder 9. The spring 5 then rotates the support 3 clockwise to its inoperative position.

Title: A method for proportioning the humidifying water in a finely divided mixture undergoing agglomeration by ignition on a continuous grate
IPC: C22B1/20
Filed: 1961-12-22
Abstract: <PICT:0966779/C1/1> In an apparatus for the sintering of a finely divided mixture on a continuous grate, the amount of humidifying water is maintained at the optimum valve by taking two successive measurements of the permeability of the mixture to a stream of air at a fixed point past which the grate moves before ignition, the second measurement being effected after the humidifying water has been increased by a known small amount; if the permeability increases between the two measurements the total amount of humidifying water is increased, if the permeability decreases the total amount of humidifying water is decreased and if the permeability is substantially unchanged the total amount of humidifying water is unchanged. Alternatively, the humidifying water may be decreased by a small amount between successive measurements; in this case, if the permeability increases the total amount of humidifying water is decreased, if the permeability increases the total amount of humidifying water is increased and of the permeability is substantially unchanged the total amount of humidifying water is unchanged.  In the arrangement shown, crushed ore and powdered fuel are fed via a mixer 5 having a water feed 6 to sintering machine 9. A hood 11 connected to a fan 14 is positioned on the upstream side of the ignition hood 12.  A mixture thickness gauge 10, an air pressure difference gauge 13 and a total air gauge 15 are all connected to a permeability calculator 19.  In operation, the permeability of the mixture is determined by the calculator 19 and fed to a memory device 20.  More water is added to the mixture at 6 and the new permeability is determined by the calculator 19 and fed to a device 21 where it is compared with the previous permeability value stored in the memory device 20.  The device then opens or closes a valve 7 in the water feed 6 until the difference between successive permeability measurements is zero; this represents the optimum water content of the mixture.  The arrangement also adjusts the water content of the mixture to the optimum if the water content of any of the mixture components alters.

Abstract: 1,068,216. Circuit assemblies. GENERAL ELECTRIC CO. Ltd. Nov. 4, 1965 [Nov. 13, 1964], No. 46317/64. Heading H1R. [Also in Divisions H3 and H4] A pair of switching circuits (1, Fig. 1, not shown) each comprising a T-network having a rectifier element (2, 3 or 7) in each limb thereof, provide selective connection of an input (at 15) to either of two outputs (at 17). A biasing potential from a source (11) is applied to the common points (4) of the T-networks; a negative biasing potential causes a network to offer a high impedance to the passage of current between the input and the respective output, while a positive biasing potential facilitates such passage of current. Rectifier elements (3) constituting components of six pairs of circuits (1) are housed in a single unit (19), while the other components of each pair of circuits (1) are housed in a separate unit (20). The single unit 19, Fig. 2, comprises a shallow rectangular box having three pairs of coaxial sockets 22 on each of its major faces to co-operate with coaxial plugs 21 on minor surfaces of separate units 20, which also comprise shallow rectangular boxes. Input and output terminals 15, 17 comprise coaxial sockets, and socket connectors 33 are provided on single unit 19 for the application of biasing voltages. The invention is described with reference to a multi-channel communication system, Fig. 3 (not shown), in which the channels are arranged in six groups associated with six I.F. signal circuits (23) which are normally connected to six R.F. transmitters (24). In the event of the failure of a transmitter (24), the corresponding I.F. circuit (23) is switched to one of two standby transmitters (25). The standby transmitters (25) may also handle occasional signals from further I.F. circuits (30), being connected thereto by a further pair of switching circuits (32). Fig. 4 (not shown) depicts the arrangements at the corresponding receiving station.

[Also in Division C3] Rigid sheets of foamed cross-linked thermoplastic polymers are prepared in an apparatus comprising two parallel belts and side pieces to form a cavity, the inlet and outlet ends being adjusted to correspond to the depth of the unfoamed and foamed sheets respectively. Two substantially parallel steel belts 16, 28 run over wheels 17 and 18 on a lower frame and 29 and 30 on an upper frame respectively. The upper frame is pivoted at 25 and the separation between the belt is adjusted by shims 71 and screw thread 73 operated by handle 82. The belts are backed by platens 59, 63 which also contain heating elements at the feed end and optional cooling tubes at the discharge end. Belts 50 running on tensioned pulley 52 and pulley 53 provide the side of the cavity. The unfoamed mixture, e.g. a thermoplastic polymer, blowing agent and cross-linking agent is fed in at the right hand end, the gap between rollers being adjusted to the depth of the sheet. The outlet end is set to the calculated depth of the foamed sheet, and the rate of motion of the belts to allow the material time to polymerize fully. Laminated foams may be prepared by passing in the unfoamed material between sheets of the material to be laminated or the side sheets of the laminate may be bonded to a preformed foam in the same apparatus.
